1. 1. On the principles of word formation in Swedish

   Författare :Gunlög Josefsson; Svenska; []
   Nyckelord :HUMANIORA; HUMANITIES; Originator; Force; Telicity; Event measurer; LF-lexicon; PF-lexicon; List of Morphemes; Property; Thing; Event; prefix; major ontological categories; suffix; compound; derivation; linking element; asymmetry; Move; Merge; Generalized Transformations; word class; inflection;

   Sammanfattning : My thesis is an attempt to give a minimalist account of word formation in Swedish. (See Chomsky (1993) and (1994).) In the main part of my thesis I demonstrate how the proposed system accounts for the central aspects of Swedish word formation. LÄS MER

   Sammanfattning : We study admissible transformations and solve group classification problems for various classes of linear and nonlinear Schrödinger equations with an arbitrary number n of space variables.The aim of the thesis is twofold. LÄS MER

4. 3. Painlevé analysis and transformations for nonlinear partial differential equations

   Författare :Ove Lindblom; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

   Sammanfattning : Nonlinear partial differential equations play a fundamental role in the description of many physical models. In order to get a complete understanding of the phenomena which are modeled it is important to obtain exact analytic solutions. LÄS MER

5. 4. Parallel Algorithms and Library Software for the Generalized Eigenvalue Problem on Distributed Memory Computer Systems

   Författare :Björn Adlerborn; Bo Kågström; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer and systems sciences; data- och systemvetenskap;

   Sammanfattning : We present and discuss algorithms and library software for solving the generalized non-symmetric eigenvalue problem (GNEP) on high performance computing (HPC) platforms with distributed memory. Such problems occur frequently in computational science and engineering, and our contributions make it possible to solve GNEPs fast and accurate in parallel using state-of-the-art HPC systems.

7. 5. The Complex World of Superstrings : On Semichiral Sigma Models and N=(4,4) Supersymmetry

   Författare :Malin Göteman; Ulf Lindström; Daniel Waldram; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-linear sigma models; extended supersymmetry; semichiral superfields; neutral hyperkähler geometry; generalized Kähler geometry; T-duality; vector multiplets; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. Analyzing the geometrical and topological properties of sigma models is necessary to understand the underlying structures of string theory. LÄS MER
